Abstract: 897,212. Testing relays. BRITISH TELECOMMUNICATIONS RESEARCH Ltd. June 11, 1958 [May 22, 1957], No. 16319/57. Class 37. [Also in Group XL (b)] In an arrangement for testing the operation of a member taking up one or other of two positions, or operated to one or the other of two states, in response to signals of binary form, for example, a relay arranged to respond to mark and space telegraph signals, the telegraph line 10 is connected at terminals 11, 12 to a relay 13 having a moving member 14 oscillated between contacts 15, 16 connected respectively to + and - battery. The input at 11, 12 is also connected to terminals 23, 24 of a C.R.T. 22 for the vertical movement of the beam which is moved horizontally by a timebase circuit 25 to provide a display of the incoming waveform. The voltage changes produced at the contacts 15, 16 are passed to a differentiating network 20 producing peaked pulses at the transitions of the member 14, and these are passed by a rectifier 21 to the control grid of the C.R.T. If the rectifier 21 is arranged for full-wave rectification, brightened spots will occur at both types of transition, i.e. mark-space and space-mark, and a marking or spacing bias of the relay will be indicated by the vertical positioning of the brightened spots relative to the maxima and minima of the displayed waveform. The elements 20, 21 may be replaced by a trigger pair circuit, and the outputs of the two anode circuits are differentiated before being applied to the control grid of the C.R.T.

Abstract: 147,547. Farrel Foundry & Machine Co., (Assignees of Schnuck, C. F., and Bowen, D. R.). July 11, 1919, [Convention date]. Stationary batch mixers with rotary stirrers; mixing by compression.-A machine for mixing and masticating rubber and similar heavy plastic material comprises a mixing-chamber with a relatively narrow constricted intermediate portion, and a device, such as a rotor provided with blades, adapted to mash the material against the walls of the chamber and to extrude it through the constricted portion and back again, alternately. The mixing-chamber 10, Fig. 1, is cylindrical and is comprised of three portions, two of which 10<a>, Fig. 4, are bolted together, and the third 10<b>, is hinged to form a discharging-door. Wedges or cams 31 operated by screws 30 rotated by a handwheel 27 enable the door to be closed tightly or opened as desired. The chamber has formed in the middle of its interior surface a rib 13, Fig. 5, which thus forms a constriction of the bore through which the rubber is forced from side to side. A shaft 11, Fig. 1, is journaled in the casing and has blades 12, Figs. 4 and 5, which conform to the shape of the end portions of the mixing-chamber. The blades are arranged on the shaft at such an angle that as the shaft rotates, the rubber is forced through the constricted part of the chamber. The face of each blade is so formed, as shown in Fig. 4. as to " mash the material against and smear it over the interior surface of the chamber." The rubber is admitted to the chamber through a hopper 22, and in order to assist in feeding the rubber inwards, one or more straps or ribs 23, Figs. 4 and 5, are attached to or formed in the inner wall of the chamber near the hopper at an angle to the edge of the blade 12. The ribs tend to prevent the rubber from rotating with the blade and direct it towards the middle of the chamber.
